[Solved] i % 1 does not give 0 in script, but manually in command line it does?
I have a piece of code that counts in a for loop but while counting I want it so whenever it is divisible by 1 to run a function. However, it keeps failing the 'checking if divisible by 1' part (it gives a different number). I just can't figure it out, unless it's some bug.
Here's a slightly edited copy of my script:
01 | for i = 0,Time, 0.1 do |
02 | Charge = i / Time |
03 | if i % 1 == 0 then |
04 | print(i, true, i % 1) |
05 | Function() |
06 | else |
07 | print(i, false, i % 1) |
08 | end |
09 | if HoldingZ == false then |
10 | break |
11 | end |
12 | wait(.1) |
13 | end |
And here's the output:
01 | > 0 true 0 |
02 | > 0.1 false 0.1 |
03 | > 0.2 false 0.2 |
04 | > 0.3 false 0.3 |
05 | > 0.4 false 0.4 |
06 | > 0.5 false 0.5 |
07 | > 0.6 false 0.6 |
08 | > 0.7 false 0.7 |
09 | > 0.8 false 0.8 |
10 | > 0.9 false 0.9 |
11 | > 1 false 1 -- Why does it not output 0? |
12 | > 1.1 false 0.1 |
13 | > 1.2 false 0.2 |
14 | > 1.3 false 0.3 |
15 | > 1.4 false 0.4 |
Now here's what happens if I do this in the command line at the bottom of Roblox Studio:
1 | print(5%1) -- Output: 0 |
What am I doing wrong? I am absolutely confused!
Thanks for helping!

I have no idea what this is happening. Fortunately, I was browsing around, and I found a replacement for the modulus (you aren't the only one having an issue with this operator):
1 | a % b = a - math.floor(a / b) * b |
It's not ideal, but hey! At least it returns the remainder. So, you could make a variable with this and write your code something like this:
1 | local remainder = i - math.floor(i / 1) * 1 |
Hope this helped!

Use math.fmod, it does exactly what you want.
01 | for i = 0,Time, 0.1 do |
02 | Charge = i / Time |
03 | if math.fmod(i,1) == 0 then |
04 | print(i, true, math.fmod(i, 1)) |
05 | Function() |
06 | else |
07 | print(i, false, math.fmod(i, 1)) |
08 | end |
09 | if HoldingZ == false then |
10 | break |
11 | end |
12 | wait(.1) |
13 | end |
